As your Depth and Elapsed Dive Time increase, segments will
add to the TLBG (Fig. 5A), and as you ascend to shallower
depths, the segments of the TLBG will begin to recede, indicating
that additional no decompression time is allowed.
The TLBG monitors 12 different nitrogen compartments simulta-
neously and displays the one that is in control of your dive. It
consists of 5 segments, the lower 4 represent No Decompression
status and the one at the top indicates a Decompression condi-
tion.
Within the available NOR Mode parameters that can be set
(described later) are a TLBG Alarm and a Conservative Factor
which, if set ON, reduces No Decompression times allowed.
FREE Dive Mode has a separate (fixed) TLBG Alarm.
While you cannot provide a guarantee against the occurrence of
decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight,
etc., to reduce the statistical risk.
When the DataMask is set to operate in NOR Nitrox mode, the
Bar Graph will represent O2 accumulation when the O2 data
screen (Alternate Display) is accessed or a High O2 condition
exists. The O2 icon and right side bar will appear (Fig. 6a).
